Nūhou - FKM Rubber vs PTFE: ʻO ia ka mea ʻoi loa ka fluorinated |BESTEFLON

ʻO ka lāʻau fluorine (FKM) he elastomer thermosetting, aʻo polytetrafluoroethylene (PTFE) he thermoplastic.ʻO nā mea ʻelua i fluorinated, i hoʻopuni ʻia e nā ʻātoma fluorine e nā ʻātoma kalapona, kahi e kū ai lākou i nā mea kemika.Ma kēia ʻatikala, hoʻohālikelike ka hopena polymer TRP i nā mea ʻelua ma waena o FKM a mePTFEe hoʻoholo ai ʻo ia ka mea fluorinated hope loa a koho i ka hopeʻO ka mea hana hose PTFE

Nā pōmaikaʻi o ka FKM rubber a me ka PTFE

Nā kumu:

FKM: Ua pilikia ka mokulele i ka wā o ke Kaua Honua II e ka leaka ʻana o nā sila nitrile, i nele i ka hana haʻahaʻa haʻahaʻa e pono ai no nā noi like ʻole.ʻO ka inertness kemika o nā paʻa fluorocarbon, ʻo ia hoʻi, he hopena kūlohelohe nā fluorinated elastomers, a i ʻole fluoroelastomers.No laila, ua hoʻomaka ke kūʻai ʻia ʻo FKM rubber i ka makahiki 1948

PTFE: I ka makahiki 1938, ua ʻike ka ʻepekema ʻo DuPont ʻo Roy Plancott i ka polytetrafluoroethylene ma ka pōʻino.Ua hoʻāʻo ʻo Plunkett me nā mea hoʻoheheʻe a mālama ʻia i loko o nā cylinders.ʻO kāna pūʻiwa, ua hōʻuluʻulu ʻia kēia mau kinoea, e waiho ana i kahi mea waxy keʻokeʻo, ʻaʻole e hoʻopili me nā mea kemika a hiki ke kū i nā wela kiʻekiʻe loa.Ua hoʻopaʻa inoa ʻo DuPont i ka hōʻailona mua o nā mea PTFE-ptfe ma 1945

ʻO ka hoʻoholo: ʻO ka hoʻomohala ʻana o ka PTFE he coincidence o kahi hopena hoihoi, i alakaʻi ai i ka hānau ʻana o kahi mea kupaianaha.Eia nō naʻe, he mea pono loa i nā makahiki kaua, ʻo FKM rubber.No kēia kumu, ʻoi aku ka maikaʻi o ka hāʻawi mōʻaukala o FKM fluoroelastomer ma kēia kaʻina hoʻokūkū

Nā waiwai:

Lapa FKM: Loaʻa i ka pāpaʻi FKM nā mea paʻa kalapona-fluorine ikaika, e hana ana i ke kemika nui loa, ka wela a me ka pale ʻana.Loaʻa i ka FKM kekahi helu ʻokoʻa o nā mea paʻa carbon-hydrogen (kahi pilina me ka wela nāwaliwali a me ke kūpaʻa kemika), akā ʻoi aku ka ikaika o ke kūpaʻa kemika ma mua o ka hapa nui o nā elastomers.

PTFE: Hoʻokumu ʻia ka Polytetrafluoroethylene me ke kaulahao kalapona, me ʻelua mau ʻātoma fluorine ma kēlā me kēia ʻātoma kalapona.Hoʻopuni kēia mau ʻātoma fluorine i ke kaulahao kalapona e hana i kahi mole mole me kahi paʻa kalapona-fluorine ikaika loa a me kahi ʻano polymer, e hana ana i ka PTFE inert i ka hapa nui o nā kemika.

'Ōlelo Hoʻoholo: Ma muli o ko lākou haku mele ʻana, ʻaʻohe paʻa kalapona-hydrogen o ka PTFE, ʻo ia ka mea i ʻoi aku ka ʻoi aku o ke kemika ma mua o ka FKM (ʻoiai ʻo FKM ke kūpaʻa mau nei i ke kemika).No kēia kumu, ʻo PTFE wale nō ke aka o FKM i kēia pōʻai

Pono:

FKM:

Laulā wela ākea (-45°C-204°C)

Kūleʻa kemika maikaʻi loa

Kiʻekiʻe kiʻekiʻe, ʻano maikaʻi

ʻO nā waiwai mechanical maikaʻi

Hiki ke hana ʻia no ka decompression pahū, CIP, SIP

PTFE:

Palena wela ākea (-30°C a +200°C)

Kemika inert

ʻOi aku ka maikaʻi o ka pale uila

Kūleʻa ke anu a me ka wela

Pili ʻole, wai ʻole

ʻO ka coefficient o friction ka mea liʻiliʻi loa ma waena o nā mea paʻa a pau

'Ōlelo Hoʻoholo: ʻAʻole hiki ke hoʻokaʻawale iā lākou i kēia pōʻai.Hāʻawi ʻo FKM i ka pale wela ʻoi aku ka nui, akā ʻaʻole hiki i ka hana o ka PTFE ma ke ʻano o ka pale kemika.A emi iki ka PTFE i ka wela, akā hāʻawi i nā ala he nui o nā waiwai non-adhesive

Nā hemahema:

FKM:

E pehu anei ia i loko o kahi mea hoʻoheheʻe fluorinated?

ʻAʻole hiki ke hoʻohana ʻia me nā metala alkali hoʻoheheʻe a kinoea paha

ʻOi aku ka nui o ke kumukūʻai ma mua o nā non-fluorocarbons ʻē aʻe

ʻO ke koho ʻana i ka FKM hewa no ka noi hiki ke hoʻopau wikiwiki

Hiki ke pipiʻi nā māka wela haʻahaʻa

PTFE:

Haʻahaʻa ikaika a ʻoʻoleʻa

ʻAʻole hiki ke hoʻoheheʻe ʻia

ʻino ka pale ʻana i ka radiation

ʻO ka paʻakikī ʻo High Shore e paʻakikī iā PTFE e sila

ʻOi aku ka nui o ka leakage o nā apo o Ptfe ma mua o nā elastomers ʻē aʻe

ʻAʻole hiki i ka inelasticity ke hoʻokomo i nā sila he nui

ʻŌlelo Hoʻoholo: Ma ka laulā, ua lanakila ʻo FKM rubber i kēia hoʻokūkū hoʻokūkū me kona ikaika kiʻekiʻe, ka maʻalahi a me ka hiki ke sila.ʻO kaʻoiaʻiʻo, inā ʻaʻole lawa wale kahi sila inert chemically, a laila he koho maikaʻi ʻo PTFE.Eia naʻe, hāʻawi ʻo FKM i ka maʻalahi ma nā ʻano āpau!

Nā noi:

FKM:

Kaʻa kaʻa

ʻO ka hana kemika

ʻAila a me ke kinoea

Mekini hana kaumaha

Nui nā mea ʻē aʻe

PTFE:

Mea hana kemika

Nā pāpaʻi

Ka lawe ʻana i nā kemika

Olelo Hooholo: He kaua make loa keia!ʻOi aku ka laulā o nā noi FKM, a hiki ke hoʻohana ʻia i kekahi mau noi kaumaha loa.Eia nō naʻe, ʻoiai nā palena, hāʻawi nā mea PTFE i ka hopena hope loa no nā noi paʻakikī loa e pili ana i ke kaomi koʻikoʻi, ka wela a me nā kemika corrosive.

Koina:

He huahana waiwai ka FKM rubber ma muli o kona haku mele 'ana a me ke kū'ē kemika.Inā ʻaʻole ʻoe e noʻonoʻo i nā waiwai kemika a me ke kūpaʻa wela, hiki iā ʻoe ke koho i kahi elastomer ʻoi aku ka liʻiliʻi.

PTFE: He huahana kiʻekiʻe nō hoʻi nā mea PTFE.Pēlā nō, inā ʻaʻole ʻoi aku ka mahana, ke kaomi, a me nā kinikona corrosive i loko o kāu noi ma mua o nā hihia koʻikoʻi loa, a laila makemake ʻia nā koho ʻoi aku ka liʻiliʻi.No ka loaʻa ʻana o ka hana hoʻopaʻa sila maikaʻi loa, hoʻopaʻa ʻia ʻo PTFE i ke kumu elastomer e hāʻawi i ke kūpaʻa paʻa.

Olelo Hooholo: ʻO FKM a me PTFE nā huahana kiʻekiʻe no nā kumu maikaʻi.Loaʻa i kēia mau mea ʻelua nā waiwai kūikawā, e wehewehe ana i ke kumukūʻai o ka hana ʻana iā lākou.Eia naʻe, pono ʻoe e hoʻomanaʻo no nā noi koʻikoʻi, hāʻawi ʻelua i nā hiʻohiʻona kūikawā.I kēia hihia, loaʻa iā ʻoe ka mea āu e uku ai, a hāʻule koke nā koho ʻokoʻa.He hoʻokele hewa kēia hope loa.

Ka hopena: Ma ka laulā, ʻo ka maʻalahi o ka FKM hāʻawi iā ia i mea pono i kēia lāhui hypothetical.ʻO ka hope loa, hāʻawi kēia mau mea fluorinated ʻelua i ke kūpaʻa kemika kūikawā a me ke kūpaʻa wela.Eia naʻe, ma ke ʻano he plastic, ʻoi aku ka paʻakikī o ka PTFE ma mua o FKM;ʻo ia wale nō ka mea kūpono no nā noi hoʻopaʻa hoʻopaʻa paʻa loa kahi e hopohopo nui ai ke kaomi kiʻekiʻe a me nā kemika corrosive.ʻO ka hoʻohana nui ʻana o FKM ma ke ʻano he mea sila, ua hōʻoia i kona lanakila!

Manaʻo mākou e hāʻawi kēia hoʻohālikelike o FKM rubber a me PTFE iā ʻoe i kahi ʻike maikaʻi aʻe o nā ʻano like ʻole o kēlā me kēia mea.Pono e hoʻokūpaʻa ʻia ʻo ke ala maikaʻi loa e koho ai i nā mea kūpono loa no kāu noi ʻana e kamaʻilio me kahi loea e hiki ke haʻi iā ʻoe i nā māka waiwai like ʻole a hoʻohālikelike i ka hopena kūpono no kāu noi.

ʻO ka mea i luna e pili ana i ka FKM a me ka PTFE pili i ka hoʻolauna ʻana, ke manaʻo nei wau e hiki ke kōkua kēia ʻatikala iā ʻoe, no ka ʻoihana Kina mākou.Nā mea hoʻolako hose PTFE, welcome to consult our products and please freely contact us at sales 07@zx-ptfe.com
